To all whom t may concern: o Y

Be it known that I, SPENCER A. CHERRY, a citizen of the United States of America, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in SpringVVheels, of which the following is a specification, reference being had therein to the accompanying drawing. n

This invention relates to spring wheels for automobiles and yother vehicles and has ,for its object the production of a simple and efficient means whereby the supporting springs for the rim of the wheel. will1 be etliciently lubricated vso as to prevent the springs from becoming worn 0r exceedingly heated which would be likely to break the springs or remove the temper therefrom.

Another object of thisv invention is they production of a simple and eiiicient `wheel which will be resilient without the use of pneumatic tires and which may be readily assembled and any part thereof replaced vshould the same become injured.

With these and other objects in view Vthis invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed. i y

In the accompanying drawings: Figure 1 is a side elevation of the wheel partly shown in section. Fig. 2 is a central vertical section Ataken on line 2 2, of Fig. 1. Fig. 3 is a section taken on line 3 3, of Fig. 1. Fig. 4 1s Y a section taken on line 4 4, of Fig. 1. Fig. 5 is a section taken on line 5 5, of Fig. 1. Fig. 6 is a side elevation of one of the springs used in connection with the present invention. Fig. 7 is a front elevation of one of the springs used in connection with the present.

invention. Fig. 8 is a side elevation of one of the spacing bolts used in connection with the device.

By referring to the drawings it will be `seen that 1 designates the hub which may be formed of any suitable or desired construction without departing from the spirit of the invention, and this hub carries a side plate 2 which is preferably formed integral there with. A cover plate 3 is adapted to be fitted upon the outer reduced end 4 of the hub 1 and carries a projecting collar 5 for constituting an e'fiicient means forfacilitating the holding of the plate 3 in engagement with the hubv 1. The plates 2 and 3 are held in proper spaced relation by -means of the spacing bolts 6 clearly illustrated'in detail in Figs. 4 and 8 of the drawings. A plurality `of these bolts 6 are arranged in staggered :relation around the hub 1l of the wheels as clearly; illustrated in Fig. 1 of the'drawings,

and these boltsl 6 carry nuts 7 upon their outerjthreaded ends 8 for firmly holding, the

bolts in their proper position. The inner y ends of the springs 9 which are provided 'with eyesl() t around the bolts 6 and'constitute an eflicient means for retaining the springs 9in enga gement with the bolts 6 ad jacent the hub of the wheel. These springs 9 are substantially S-shaped having'a double bowA and aneye 11 is formed .upon the outer end of each spring, which eye is adapted to be engaged by means of a bolt 12 carried by the rim 13y of the wheel.y This rim 13 carries a felly 14 upon which a solid rubber tire 15 is mounted. The felly 14 is provided with a Vpair 'of inwardly projecting, flanges 16 through which the' bolts 12 pass, and it will be seenv that the flanges 16 will constitute a protecting means for the eyes 11 of the springs 9.v Attention is'invited to Figs. 3 and 5 of the drawings for it will be seen that these springs9 are so positioned between the plates 2 and 3as to allow a slight space between tlie edge of the springs 9 and the inner faces of the plates 2 and 3.

K. A packing of oiled wool or other material 17 is placed between the spokes 9 as clearly illustratedein Figs. 1, 2 and 5 for the purpose of efficiently lubricating the springs at the point where the same would be likely to bear against the inner faces of the plates 2 and 3. It should be understoodthat suificient distance is left between the plates 2 and 3 and the edges of the springs 9 to prevent any great amount of which have their threaded ends 21 passing vkthrough the plates 2 and and are retainedin their proper position by means of the nuts. 22 placed thereon.k

'In assembling the wheelvit should be understood that thespokes 9 are secured to the lhub in staggered relation, being'fastened at ltliejliub'and rimpby tlierespective bolts 6 ,n and l2. The plate 3 is bolted vfirmly against the shoulder`23 of the hub l, andit should be understood that the shoulder will give y considerable lateral strength and' form a housingV in which the spokesare freeV to eX- V pandr and-contract under the variance of f temperature which ,ma-y be likely to aii'ect the ditlerent parts of ymetal out of which the deviceis formed,V 1,

lt should be understood that V,when the 'Aweightis4 applied at the hub, the spokes beneath the hub will be compressed while those opposite the hub are under a tension. kSince the spokes are substantially S-shape in construction it will be understood that thehub kwill be'free to change position under variable loads. YIt should also be understood that the packing wool between the several parts will constitute a very simple and eiicient means for 'keeping the wheel thoroughly lubricated. y

lt, of course, should be understood that the felly 14 may be kheld firmly upon the rim 1.3 by means of tlie'bolts 24er other suitable fastening means which may be rfound convenient. l l

Having thus described the invention what is claimed as new,fis:- j

yl. n A wheel of the class described comprising a hub, a,y plurality of plates carried thereby, a plurality of springspokes carried by said plates, a brou's oiled packing positioned between said spokes near the inner ends thereof, a resilient plug itting between each spoke andprovided with overhanging side flanges for itting over the outer edges of said plates, a felly engaging said spokes, and bolts carried by said plates and passing through said plugs for rmly holding the saine against accidental removal from engagement with said plates and sealing the space between the outer edges of said plates and between said spokes.

2. A wheel of the class described comprising a hub,a plurality of spokes carried by said hub, a lubricated packing placed in said hub between said spokes, a resilient plugvpositioned between said spokes and constituting a retainer for said lpacking and also a resilient buffer between said spokes, a felly engaging said spokes, and means engaging said spokes for holding the same against accidental removal from said hub. a
